Sen. Ted Cruz (R-TX) on Tuesday introduced a bill to prevent midair collisions, six months to the date after a Black Hawk helicopter crashed into a passenger jet approaching Ronald Reagan Washington National Airport, killing 67 people.

The legislation aims to mandate the installation of anticollision technology on all military flights and require the Army to keep ADS-B Out and ADS-B In signals on at all times. Operating independently of air traffic control, the system broadcasts the aircraft’s position, altitude, speed, and other data.
